In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0050] The present application provides a control method for vehicle anti-theft activation. The following is a detailed description of the pre-tank oil quality inspection system of the present application in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0051] The present application provides a control method for vehicle anti-theft activation, which is mainly applicable to the following scenarios: (1) When a user discovers that the vehicle has been stolen, the user can remotely control the vehicle's anti-theft function, obtain the anti-theft password through the anti-theft function, and execute the vehicle anti-theft control method of the present application through the vehicle's anti-theft function and controller; (2) If the vehicle's controller crashes during driving and then restarts, the anti-theft function module of the vehicle control system re-obtains the anti-theft function password through the controller wake-up protocol, and executes the vehicle anti-theft control method of the present application through the vehicle's anti-theft function and controller.

[0052] See also Figure 1 As shown, the present application provides a control method for vehicle anti-theft activation, comprising:

[0053] S11, obtaining and identifying the anti-theft function password;

[0054] S12, identifying the anti-theft function password;

[0055] If the anti-theft function password is correct, S20, a deactivation signal is issued;

[0056] If the anti-theft function password is incorrect, S30, determining the driving state of the vehicle;

[0057] When the vehicle driving state is a safe state, S40, an activation signal is issued;

[0058] When the vehicle driving state is in an unsafe state, S20, a deactivation signal is issued.

[0059] When the anti-theft function password is wrong and the vehicle is in a safe state, the anti-theft function module sends an activation signal, and the controller controls the motor to stop working, so that the vehicle can stop. When the anti-theft function password is wrong but the vehicle is in an unsafe state, the anti-theft function module sends a deactivation signal. After receiving the deactivation signal, the controller will not control the motor to stop working, so as to avoid the vehicle from stopping suddenly in an unsafe state, thereby improving the safety of the vehicle during driving. When the user finds that the vehicle has been stolen, the anti-theft function of the vehicle can be remotely controlled, the anti-theft password can be obtained through the anti-theft function, and the control method of vehicle anti-theft activation can be executed through the anti-theft function and the controller of the vehicle. When the vehicle is in a safe state, the anti-theft function module sends an activation signal, and the controller controls the motor to stop working, so that the vehicle can stop, thereby avoiding theft.

[0060] See also Figure 2 As shown, in an optional embodiment, before determining the vehicle driving state in S30, the method further includes:

[0061] S50: issuing a pre-activation request.

[0062] After receiving the pre-activation request, the controller will be in the pre-activation state. In the pre-activation state, the controller will be ready to receive activation signals and deactivation signals, so that the controller can respond to activation signals and deactivation signals more quickly. When the anti-theft function password is wrong and the vehicle is in a safe driving state, the controller can quickly control the motor to stop working to prevent the vehicle from being stolen.

[0063] See also Figure 3 As shown, in an optional embodiment, S30, determining the driving state of the vehicle includes:

[0064] S31, obtaining vehicle operating parameters;

[0066] The vehicle is provided with a sensor for detecting vehicle operating parameters. In some embodiments, when the anti-theft function password is incorrect, the vehicle operating parameters are obtained through the sensor, and the vehicle driving state is determined based on the operating parameters. In other embodiments, the vehicle operating parameters are obtained in real time through the sensor, and when the anti-theft function password is incorrect, the vehicle driving state is determined based on the current vehicle operating parameters.

Through the above settings, a comprehensive judgment can be made on the vehicle driving state through various types of sensors, which is applicable to various complex vehicle driving conditions and improves the safety of the vehicle during driving.

[0073] When all types of parameters to be tested meet the corresponding safety thresholds, S40, an activation signal is issued;

[0074] When any type of the measured parameter does not meet the corresponding safety threshold, S20, a deactivation signal is issued.

[0075] Specifically, the multiple types of vehicle operating parameters may be vehicle speed, the distance between the vehicle and the front and rear vehicles, vehicle position information, vehicle slope angle information, etc. In some embodiments, the priority relationship of at least two types of parameters to be measured may be sorted according to the degree of influence of each type of vehicle operating parameter on the safety state of the vehicle driving state, that is, the vehicle operating parameter with the greatest influence on the safety state of the vehicle driving state has the highest priority, and as the influence of the vehicle operating parameter on the safety state of the vehicle driving state decreases, the priority of the vehicle operating parameter also decreases.

[0076] See also Figure 5 As shown, in an optional embodiment, S3212, according to the priority relationship, step by step, obtaining and judging whether all types of parameters to be tested meet the safety threshold, including an execution method applicable to any two adjacent priority types of parameters to be tested, the execution method includes:

[0077] S321, obtaining a first parameter to be tested of a parameter with a higher priority;

[0078] S322, determining whether the first parameter to be measured meets the corresponding first safety threshold;

[0079] When the first parameter to be measured meets the first safety threshold, S323, obtaining a second parameter to be measured with a lower priority, S324, determining whether the second parameter to be measured meets the corresponding second safety threshold;

[0080] When the first parameter to be measured does not meet the first safety threshold, S20, a deactivation signal is issued.

[0081] In the specific implementation process, the first parameter to be measured, the second parameter to be measured and the third parameter to be measured with decreasing priority are taken as an example. The execution method includes:

[0082] Obtaining a first parameter to be measured;

[0083] Determining whether the first parameter to be measured meets the corresponding first safety threshold;

[0084] When the first parameter to be measured does not meet the first safety threshold, sending a deactivation signal;

[0085] When the first parameter to be measured meets the first safety threshold, obtaining the second parameter to be measured, and determining whether the second parameter to be measured meets the corresponding second safety threshold;

[0086] When the second parameter to be measured does not meet the second safety threshold, sending a deactivation signal;

[0087] When the second parameter to be measured meets the second safety threshold, obtaining the third parameter to be measured, and determining whether the third parameter to be measured meets the corresponding third safety threshold;

[0088] When the third parameter to be measured does not meet the third safety threshold, sending a deactivation signal;

[0089] When the third parameter to be measured meets the third safety threshold, the vehicle driving state is judged to be a safe state, and an activation signal is sent.

[0090] In an optional embodiment, at least two types of parameters to be measured include, in descending order of priority: vehicle speed, vehicle position information, and vehicle ramp angle information.

[0091] See also Figure 6 As shown, the execution method includes:

[0092] Get vehicle speed information;

[0093] Determine whether the vehicle speed meets the corresponding vehicle speed safety threshold;

[0094] When the vehicle speed does not meet the vehicle speed safety threshold, a deactivation signal is issued;

[0095] When the vehicle speed meets the speed safety threshold, the vehicle position information is obtained, and it is determined whether the vehicle position is on the expressway;

[0096] When the vehicle is located on a highway, a deactivation signal is issued;

[0097] When the vehicle is not located on a highway, the ramp angle information of the vehicle body is obtained, and it is determined whether the ramp angle of the vehicle body meets the corresponding ramp angle safety threshold;

[0098] When the ramp angle of the vehicle body does not meet the ramp angle safety threshold, a deactivation signal is issued;

[0099] When the ramp angle of the vehicle body meets the ramp angle safety threshold, the vehicle driving state is judged to be a safe state and an activation signal is issued.

[0100] A comprehensive judgment is made on the driving state of the vehicle through various types of sensors, and judgments are made for different driving conditions of the vehicle, such as when the vehicle is in a high-speed driving state, in an area of ​​a highway where an emergency stop is not possible, and in a situation where the slope is large. When the vehicle speed is high, an emergency stop may cause injuries to the occupants of the vehicle or cause a collision with the vehicle behind, which has a greater impact on the safety state; when the vehicle speed does not exceed the vehicle speed safety threshold but the vehicle is on a highway, parking may cause a collision with the vehicle behind, etc., which has the second greatest impact on the safety state; when the vehicle speed does not exceed the vehicle speed safety threshold, the vehicle is not on a highway but the ramp angle of the vehicle is large, parking may cause the vehicle to slide, which has less impact on the safety state of the vehicle in this embodiment. Through the above-mentioned settings, the risk of an emergency stop of the vehicle in an unsafe state is reduced, and the safety of the vehicle driving process is improved.

[0101] See also Figure 7 As shown, S321, determining the vehicle driving state according to at least one type of vehicle operating parameter, includes:

[0102] S341, selecting at least two types of parameters to be measured from multiple types of vehicle operating parameters;

[0103] S342, obtaining all types of parameters to be tested;

[0105] When all types of parameters to be tested meet the safety threshold, S40, an activation signal is issued;

[0106] When any of the parameters to be measured does not meet the safety threshold, S20, a deactivation signal is issued.

[0107] By synchronously acquiring at least two types of parameters to be tested and judging whether all types of parameters to be tested meet the corresponding safety thresholds, when any type of parameter to be tested does not meet the safety threshold, the vehicle's anti-theft function module can send a deactivation signal to the controller, which is beneficial to reducing the process of parameters to be tested that need to be judged and speeding up the activation of vehicle anti-theft.

[0108] The present application also provides a vehicle control system, in which a vehicle controller is used to execute the automobile anti-theft method as in the first aspect, and the vehicle control system includes an anti-theft function module and a controller, wherein the anti-theft function module is used to obtain and identify an anti-theft function password and determine the driving status of the vehicle, and the controller is electrically connected to the anti-theft function module, and the controller is used to connect to a motor and control the motor.

[0109] The anti-theft function module is used to obtain and identify the anti-theft function password and determine the driving status of the vehicle. Through the electrical connection between the anti-theft function module and the controller, the anti-theft function module sends an activation signal or a deactivation signal to the controller. When the controller receives the activation signal, the motor is controlled to stop working to prevent the vehicle from being stolen. When the controller receives the deactivation signal, the motor will not be controlled to stop working, so as to avoid the vehicle from stopping suddenly in an unsafe state, thereby improving the safety of the vehicle during driving.

[0110] The present application also provides a vehicle, the vehicle comprising the vehicle control system according to the second aspect.

[0111] In this application, the vehicle controller will restart after a crash, and the anti-theft function module of the vehicle control system will re-acquire the anti-theft function password through the controller wake-up protocol. Through the above vehicle control system, when the vehicle is in a safe state, the vehicle can stop driving in time to avoid theft.
